TBS12S / TBS12S-32 – Solar panel powered LoRaWAN RTU for SDI-12 sensors

TBS12S / TBS12S-32 are part of a range of solar panel powered outdoor LoRaWAN RTU. They have been designed to cope with applications where SDI-12 maximum range is a limitation by leveraging the long-range capability of LoRa. TBS12S / TBS12S-32 are delivered within their IP67 rated Fibox housing along with an optional fixture to tie them to a pole. Their connector allows plugging directly one SDI-12 sensor or TBS04 SDI-12 junction box would multiple SDI-12 sensors need to be locally deployed.
They are powered through a rechargeable battery supplied by an integrated solar panel.
The embedded LoRa modem supports both low (433/470MHz) and high (868/915MHz) LoRa radio bands, which makes TBS12S-32 suitable to be used anywhere without having to replace the RF board.
While TBS12S provides all the basic required SDI-12 measurements and LoRaWAN reporting capabilities, TBS12S-32 is designed to address more demanding applications thanks to its large internal storage, time synchronization/retention and its ability to be remotely controlled.
TBS12S-32 is deployed as a unique node into a typical LoRaWAN network architecture, sending its packets to the gateway that relays them to the LoRaWAN server over a TCP/IP connection:
